Description

Technical Field

[0001] This utility model relates to the field of automated packaging technology, and in particular to a bottle turnover structure for a labeling machine. Background Technology

[0002] Labeling machines are indispensable automated equipment in modern industrial production. They are widely used in production lines in industries such as food, beverage, pharmaceuticals, and daily chemicals. Their main function is to affix labels to product packaging to facilitate product identification, tracking, and management.

[0003] Traditional bottle turnover structures for labeling machines are typically designed with fixed sizes and shapes, making it difficult to adapt to different types and sizes of bottles. During production, if multiple bottle types need to be processed, it is often necessary to stop the machine for equipment adjustments or parts replacements. This not only reduces production efficiency but also increases operational difficulty and labor costs. Therefore, those skilled in the art have provided a bottle turnover structure for labeling machines to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bottle turnover structure for labeling machines. This structure uses a rotating mechanism to clamp and rotate bottles of different shapes, thereby improving the flexibility of the production line and the utilization rate of the equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bottle body turnover structure for a labeling machine, including a conveyor belt, a fixed seat is provided at the rear center of both sides of the conveyor belt, a groove is provided at the center of the side of the two fixed seats that are close to each other, a rotating structure is provided at the upper end of the upper surface of the two fixed seats, and a material distribution structure is provided at the upper center of one side of the conveyor belt.

[0006] The rotating structure includes two first rotary motors, each located at the lower center of two grooves. Each first rotary motor has a threaded rod at its output end, and a moving rod is threadedly connected to the outer side of each threaded rod. A rectangular seat is located at the center of the side of the two moving rods that are close to each other. A second rotary motor is located on the upper surface of the rectangular seat, and a first hydraulic cylinder is located on the lower surface of the rectangular seat. The first hydraulic cylinder passes through the lower surface of the rectangular seat and extends into the interior of the rectangular seat. The output end of the first rotary motor is fixedly connected to the center of the upper surface of the first hydraulic cylinder, passing through the upper surface of the rectangular seat. A circular block is located at the center of the output end of the first hydraulic cylinder. Three fixing blocks are arranged in a triangular pattern at the center of the lower surface of the rectangular seat. Connecting blocks are fitted at the lower center of both sides of the three fixing blocks. The other ends of the connecting blocks are fixedly connected to the outer side of the circular block. Clamping seats are located at the lower ends of the three fixing blocks and the lower surfaces of the connecting blocks.

[0007] Through the above technical solution, the two first rotary motors are started to move the moving rod and rectangular seat downwards, so that the clamping seat is aligned with the bottle mouth. Then, the first hydraulic cylinder is controlled to retract, and multiple connecting blocks rotate on the fixed block to clamp the clamping seat towards the center. After clamping, the second rotary motor is controlled to drive the first hydraulic cylinder to rotate, thereby causing the bottle clamped by the clamping seat to rotate. Through the rotation structure, the device can clamp and rotate bottles of different shapes, improving the flexibility of the production line and the utilization rate of the equipment.

[0008] Furthermore, the material distribution structure includes a fixed plate located at the upper front center of one side of the conveyor belt. A first gear is provided at the front and rear center of the upper surface of the fixed plate. Rubber strips are inclinedly arranged on the upper surface of the two first gears. A second hydraulic cylinder is provided at the lower center of the front surface of the fixed seat on one side. A moving strip is provided at the center of the output end of the second hydraulic cylinder. Multiple racks are arranged in a straight line at the center of the other side of the moving strip. A gear column is provided at the front center of the lower surface of the first rotary motor. The gear column passes through the lower surface of the fixed plate and is fixedly connected to the first gear at the front.

[0009] Through the above technical solution, the second hydraulic cylinder is activated, the rack drives the gear column to rotate, and the rotation of the gear column drives the first gear at the front to rotate. The rotation of the first gear at the front causes the rubber strip at the front to open, allowing the first bottle to move along the conveyor belt. When the first gear at the front rotates and opens the rubber strip at the front, since the first gear at the front meshes with the first gear at the rear, the rotation of the first gear at the front causes the first gear at the rear to rotate, but in different directions. The rubber strip at the rear will intercept the first bottle on the conveyor belt to buffer it. When the rubber strip at the front intercepts, the rubber strip at the rear no longer intercepts, allowing the first bottle to continue moving. The material distribution structure ensures that the bottles move in a predetermined order, avoiding misalignment or blockage caused by excessive speed or collision, thus improving the stability and reliability of the production line.

[0010] Furthermore, the six connecting blocks are divided into three groups. Each group of connecting blocks has a threaded post at the rear of the upper center of one side. The three threaded posts pass through each group of connecting blocks and the three fixing blocks in sequence and extend to the other side wall of each group of connecting blocks. The three fixing blocks and the three groups of connecting blocks are rotatably connected by the three threaded posts.

[0011] Through the above technical solution, the threaded column enables the connecting block and the fixed block to rotate, which meets the rotation requirements of the rotating structure, while fixing the connecting block and the fixed block and improving the stability of the device.

[0012] Furthermore, each of the three threaded posts has a nut threaded onto both ends;

[0013] The above technical solution uses nuts to prevent the threaded post from falling off and affecting the operation of the device.

[0014] Furthermore, the plurality of racks and gear shafts mesh with each other;

[0015] Through the above technical solution, the rack and the gear column mesh with each other, thereby enabling the rack to move back and forth and rotate the gear column.

[0016] Furthermore, the two first gears mesh with each other;

[0017] Through the above technical solution, the two first gears mesh with each other, so that the rotation of the first gear at the front can drive the first gear at the rear to rotate.

[0018] Furthermore, the two first rotary motors rotate in opposite directions, while the two threaded rods have the same thread direction;

[0019] The above technical solution ensures that the two moving rods move in the same direction during rotation by controlling the rotation direction and the thread direction.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the bottle turnover structure of the labeling machine ensures that the bottles move in a predetermined order through the material distribution structure, avoiding misalignment or blockage caused by excessive speed or collision, and improving the stability and reliability of the production line.

[0022] 2. In this utility model, the rotating structure allows the device to clamp and rotate bottles of different shapes, improving the flexibility of the production line and the utilization rate of the equipment. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1-4 An embodiment of this utility model is provided: a bottle body turnover structure for a labeling machine, including a conveyor belt 1, a fixed seat 2 is provided at the rear center of both sides of the conveyor belt 1, a groove 3 is provided at the center of the side of the two fixed seats 2 that are close to each other, a rotating structure 4 is provided at the upper end of the two fixed seats 2, and a material distribution structure 5 is provided at the upper center of one side of the conveyor belt 1.

[0031] like Figure 2 and 4As shown, the rotating structure 4 includes two first rotary motors 401, which are located at the lower center of the two grooves 3 respectively. Each first rotary motor 401 has a threaded rod 402 at its output end. A moving rod 403 is threadedly connected to the outer side of each threaded rod 402. A rectangular seat 404 is located at the center of the side of the two moving rods 403 that are close to each other. A second rotary motor 405 is located on the upper surface of the rectangular seat 404. A first hydraulic cylinder 406 is located on the lower surface of the rectangular seat 404, penetrating the lower surface of the rectangular seat 404 and extending into the interior of the rectangular seat 404. The output end of the first rotary motor 401 is fixedly connected to the center of the upper surface of the first hydraulic cylinder 406, penetrating the upper surface of the rectangular seat 404. A circular block 407 is located at the center of the output end of the first hydraulic cylinder 406. A triangular arrangement of [missing information] is located at the center of the lower surface of the rectangular seat 404. Three fixed blocks 408 are provided, and connecting blocks 409 are fitted on the lower center of both sides of the three fixed blocks 408. The other end of the multiple connecting blocks 409 is fixedly connected to the outside of the circular block 407. Clamping seats 410 are provided on the lower end of the three fixed blocks 408 and the lower end surface of the multiple connecting blocks 409. The two first rotary motors 401 are started to move the moving rod 403 and the rectangular seat 404 downward, so that the clamping seat 410 is aligned with the bottle mouth. Then, the first hydraulic cylinder 406 is controlled to retract, and the multiple connecting blocks 409 rotate on the fixed blocks 408 to clamp the clamping seat 410 towards the center. After clamping, the second rotary motor 405 is controlled to drive the first hydraulic cylinder 406 to rotate, thereby driving the bottle clamped by the clamping seat 410 to rotate. Through the rotation structure 4, the device can clamp and rotate bottles of different shapes, improving the flexibility of the production line and the utilization rate of the equipment.

[0032] like Figure 1 and 3As shown, the material distribution structure 5 includes a fixed plate 501, which is located at the upper front center of one side of the conveyor belt 1. A first gear 502 is provided at the front and rear center of the upper surface of the fixed plate 501. Rubber strips 503 are inclinedly arranged on the upper surfaces of both first gears 502. A second hydraulic cylinder 504 is located at the lower center of the front surface of the fixed seat 2 on one side. A moving strip 505 is located at the center of the output end of the second hydraulic cylinder 504. Multiple racks 506 are arranged in a straight line at the center of the other side of the moving strip 505. A gear column 507 is located at the front center of the lower surface of the first rotary motor 401. The gear column 507 passes through the lower surface of the fixed plate 501 and is fixedly connected to the front first gear 502. Controlling the second hydraulic cylinder 504 to start causes the racks 506 to drive the gear column 507 to rotate. The rotation drives the first gear 502 at the front to rotate, which in turn opens the rubber strip 503 at the front, allowing the first bottle to move along the conveyor belt 1. When the first gear 502 at the front rotates and opens the rubber strip 503 at the front, the first gear 502 at the front meshes with the first gear 502 at the rear. The rotation of the first gear 502 at the front causes the first gear 502 at the rear to rotate, but in different directions. The rubber strip 503 at the rear will intercept the first bottle on the conveyor belt 1 to buffer it. When the rubber strip 503 at the front intercepts, the rubber strip 503 at the rear stops intercepting, allowing the first bottle to continue moving. The material distribution structure 5 ensures that the bottles move in a predetermined order, avoiding misalignment or blockage caused by excessive speed or collision, thus improving the stability and reliability of the production line.

[0033] The six connecting blocks 409 are divided into three groups. Each group of connecting blocks 409 has a threaded post 411 at the rear of the upper center of one side. The three threaded posts 411 pass through each group of connecting blocks 409 and the three fixing blocks 408 respectively and extend to the other side wall of each group of connecting blocks 409. The three fixing blocks 408 and the three groups of connecting blocks 409 are rotatably connected by the three threaded posts 411. The threaded posts 411 enable the connecting blocks 409 and the fixing blocks 408 to rotate, which satisfies the rotation requirements of the rotating structure 4. At the same time, they fix the connecting blocks 409 and the fixing blocks 408, improving the stability of the device.

[0034] Each of the three threaded posts 411 has a nut 412 threadedly fitted at both ends. The nuts 412 prevent the threaded posts 411 from falling off and affecting the operation of the device.

[0035] Multiple racks 506 mesh with each other and gear post 507, thereby enabling the racks 506 to move back and forth and causing the gear post 507 to rotate.

[0036] The two first gears 502 mesh with each other, so that the rotation of the first gear 502 at the front can drive the first gear 502 at the rear to rotate.

[0037] The two first rotary motors 401 rotate in opposite directions, and the two threaded rods 402 have the same thread direction. By controlling the rotation direction and the thread direction, the two moving rods 403 move in the same direction when rotating.

[0038] Working principle: When the device is in use, the second hydraulic cylinder 504 is first started. The rack 506 drives the gear column 507 to rotate. The rotation of the gear column 507 drives the first gear 502 at the front to rotate. The rotation of the first gear 502 at the front causes the rubber strip 503 at the front to open, allowing the first bottle to move along the conveyor belt 1. When the first gear 502 at the front rotates and opens the rubber strip 503 at the front, since the first gear 502 at the front meshes with the first gear 502 at the rear, the rotation of the first gear 502 at the front causes the first gear 502 at the rear to rotate, but in different directions. The rubber strip 503 at the rear will intercept the first bottle on the conveyor belt 1, buffering it. When the rubber strip 503 at the front intercepts, the rubber strip 503 at the rear no longer intercepts. The first bottle continues to move, and the material distribution structure 5 ensures that the bottles move in a predetermined order, avoiding misalignment or blockage caused by excessive speed or collision, thus improving the stability and reliability of the production line. Then, the two first rotary motors 401 are started to move the moving rod 403 and the rectangular seat 404 downward, so that the clamping seat 410 is aligned with the bottle mouth. Then, the first hydraulic cylinder 406 is controlled to retract, and multiple connecting blocks 409 rotate on the fixed block 408 to clamp the clamping seat 410 towards the center. After clamping, the second rotary motor 405 is controlled to drive the first hydraulic cylinder 406 to rotate, thereby driving the bottle clamped by the clamping seat 410 to rotate. Through the rotation structure 4, the device can clamp and rotate bottles of different shapes, improving the flexibility of the production line and the utilization rate of the equipment.

[0039] The second rotary motor 405 is a hybrid stepper motor that controls its movement by receiving digital pulse signals. Each pulse signal corresponds to a step angle. By changing the frequency of the pulse signal, the speed of the motor can be controlled. This is a commonly used technique in existing transmission structures, and will not be elaborated on here.

[0040] Two first rotary motors 401 send start commands through a main control unit. The main control unit sends a synchronous start signal to the drivers of the two motors to ensure that the two first rotary motors 401 receive the start signal at the same time, thereby achieving synchronous start. This is a common technical means in existing control structures and will not be elaborated on here.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
